To all whom it may concern.-

lle it known that I, Samuel. R. Tanaammz, a citizen of the United States, and resident of Lonsdale, Cumberland township, county of Providence, State of Rhode Island, have invented an Improvement in Traverse-Motions for Yarn-Spinning Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing represeating like parte.

l :sbobb n preserve continuity of vao his invention relates to a traverse motion for yarn spinning apparatus of the type wherein the varn is -first wound u'ion tie in to` form a primary win ing or bunch," and thereafter a secondar or main winding of the yarn is laid upon t e bobbin to c omplete the building of the yarn-mass thereon.

Bobbins so wound are designed for use in automatic fillinz-replenishing looms wherein the change of lling is effected through the instrumentality of u fccler when the urn has been woven otl' to n piedetermine extent, the primary winding or bunch thcn containing n sufficient len th of the yarn to liing when filling re lenishment is e ected.

mma of thin type are well known in tha art. and require no further description herein.

My present invention has for its general object the production of a traverse motion of the character above specified, and has for its more particular object the simplification and improvement in various features of construction of the traverse motion forming the subject-hunter of United States Patent No. 040,399. granted February 15 1010 to J'. F. Mula-inl. In said ntent the bunch is formed bv or through t e ooperation of a bunch-building cani with a' cam-roll or follower carried by the builder-muito give the desired short traverse to the ring-rail, and by means of transmitting connections between the cam-shaft and a threaded hub, co rating with the shaft on which the foi. ower is mounted. such hub is revolved to move the follower laterally oat of engagement with the bunch-building cam when the bunch is'colnpleted. T hereu n the hereto ore A'ino rative main bui ding cam is brought into coperatiou with its own folower, carried by 'the builder-arm, and the main or'servioe winding of yarn is laid immuun er mun retin. anneau ma .my amano.' amai n. 'uno-lo.

I Patented Nov. 1, 1910.

By the construction referred to I attain i the desired results by very simple and drcct-actlng mechanism, as will be made ape parent hereinafter. I have also provided simple means for regulating the amount of yarn to hc laid in the bunch winding.

The various novel features of my invention will be full described in the subjoined s ication an particularly pointed out in t e following claims.

In the present embodiment of m invention .the construction is auch that t e rilgrail rises and falla with the aacentand' escent, tively, of the oscillating arm of the bui derfmotlon.

- as the fo @more i un windin 36, as shown, and a very symmetrica forni is given to the com leted yarnnnss, and the yarn will weave o better, while more yarn can be laid than if the main winding started at the top of the bunch, as in the Muheiiu structure before referred to. -In other words the lowest position ot' the builder-arm as it oscillateo during bunch-winding is substantially the same as durii the main winding.

Shoo! the bunch-winding follower lenve its cam when at one of its low points, ne for imitnnoe when the parte are in the iosttion shown in Fig'. 2, there will be a s ight sudden u lift or jump of the builder-arm llower 25 rises the short distance necessary to engage its cam 2.6 at one' of its low points, ut such jump is not objectionable, and as the cam 26 rotates the yarn will be carried down to substantially the bottom of the bunch by the descent of the ring-rail. Thus by employing .similarly shaped and symmetrically located cams for etfectin the bunch and, main windin I am ena led to make the lower endso the bunch and main windings at substantinlly the same height on the bobbin.

By effecting the disengagement of the bunch-building cam und its follower throu h the direct coperation of one with the ot er I secure a very siinlile nnd ellicient construction and an abso utely direct action, eliminating a truin of actuating mechanism between the cnin and follower to ev'ect the movement of the hitter across the face of its cam.

As the bunch-winding progresses there will be some gain of the traverse, duc to the pick-wheel and ceedingly slight as t ie stroke of the builderarm during auch winding is very short, but when tlielonger stroke durin main winding is imparted y the cuni 20 t e regulnr gain will be effected as the connection 10 is grudua'lllyl let oill by the winding drum..

e boss or hub 27 is made thick enough' to admit of adjustment of the follower 31 for a bunch of maximum capacity without interference with the cam 2t?. as will be apparent froin an inspection of Fi 8.

Various changes or modifications in details'of construction and arrangement may e `be made by lthose skilled in the art withdas out `departin from the s irit and scope of my invention as set foi't in the cliiiins annexed hereto.
